Fortran and Pascal do that.  Maybe others.

But that raises a potential conflict with another proposed magical
meaning of the subname within the sub: as a label for the beginning
of the sub.  I.e.

	sub foo {
		bar();
	}

is effectively

	sub foo {
	foo:
		bar();
	}

so that, for example, redo works kinda like the perl5 goto &foo:

	sub foo {
		bar();
		redo; # which is shorthand for:
		redo foo; # like goto &foo;
	}

Proposals along these lines came up in the thread "$a in @b",
in the subsequent discussion of RFC 199, and probably in other
threads.
